As Mark Briggs, store image director at Harrods explains: "These exquisite dresses are really one-of-a-kind fashion items from some of the most celebrated and collected designers this century. They caused a huge amount of excitement when they were first showcased in the Harrods windows and we're sure fashion aficionados around the world will be thrilled with the opportunity to own something so utterly unique."

"The rarity of these items mixed with the global appeal of Disney Princesses will make these extremely sought-after, and we expect much interest from around the world" said Christie's vintage couture specialist Clare Borthwick.

The late Walt Disney first visited Great Ormond Street Hospital in 1951, and in 2008 his company formally pledged to raise £10 million for its charity.
